PILE FABRIC.

Specification of Letters Patent.

Patented May 4, 1915.

Application filed July '7, 1914. Serial N 0. 849,405.

To all whom it may concern Be it known that I, ALBERT W. BINZ, citizen of the United States,'residing in the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in File Fabrics, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in cut pile fabrics employing pairs of binding warp threads arranged in adjacent sets of three pairs each, weft threads interwoven with the pairs of warp threads, and pile threads interwoven with the weft threads and having pile ends held spaced from each other in the direction of the warp by the weft threads, and held spaced from each other in the direction of the weft by the pairs of warp threads.

The object of my invention is to weave such fabrics in a novel manner, first, whereby the pile ends may be more evenly distributed over the pile face of the fabric so as to produce less variation in the spaces between the pile ends than heretofore, for the production of a superior fabric; secondly, whereby pile ends within each set of pairs of warp threads will extend from the back of the fabric to the pile face thereof between each and every two adjacent weft threads to prevent the backing cloth of the interwoven warp and weft threads from grinning through the spaces between the pile ends; thirdly, whereby the weft threads may be maintained in substantially the same horizontal plane and the pile ends caused to project from the backing cloth substantially at right angles thereto; fourthly, whereby the length or quantity of the pile threads buried in the backing cloth may be lessened to reduce the quantity of pile threads employed for a given number of pile ends; fifthly, whereby the lengths of pile threads floating over adjacent weft threads may be reduced; sixthly, whereby the fabric may be woven double and afterwards cut into two separate fabrics; and, seventhly, whereby various novel advantages are attained.

To these ends, my invented fabric consists of the threads and the combinations and arrangements of them hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention: Figure 1, is a section through my improved fabric, taken in the direction of the warp threads and illustrating my invention as embodied in a fabric woven double to be afterwards cut on the line w-m into two separate fabrics. Fig. 2, is a section on line 22 of Fig. 1. Fig. 3, is a plan of my improved fabric as seen from above the upper or pile face thereof, the same being a plan of the lower half of Fig. 1, after cutting the pile threads on the line w-w.

Referring first to Figs. 1 and 2 of the drawings, A and B designate the spaced upper and lower backing cloths of interwoven warp and weft threads, and 3 designates the pile threads interwoven with the threads of the backing cloths and extending through the spaces between them. When the fabric is Woven as illustrated in Figs. 1 and 2 the pile threads 3 extend continuously through the same and when the double fabric is cut on the line wm and the upper half inverted, the two halves or fabrics will be substantially alike and each pile thread 3 will be cut into a number of short pile threads, each having two pile ends 4 projecting from the backing cloth in which the body thereof is interwoven with the weft threads.

Referring now to the lower half of Fig. 1, the lower half of Fig. 2, reading these views as out on the line w-m, and referring also to Fig. 3, I shall now describe my improved finished cut pile fabric. 5 designates the weft threads, 6, 7 and 8 the binding warp threads which are interwoven with the weft threads 5, and 3 the short pile threads which are interwoven with the weft threads 5 and have their pile ends 4 extending from the backing and forming the pile face of the fabric. The binding warp threads 6, 7 and 8 are arranged in adjacent pairs and the pairs are arranged in adjacent sets S of three pairs each, '6 designating the threads of one pair, 7 the threads of another pair and 8 the threads of the third pair of a set, as clearly, shown in Fig. 3. The two binding warp threads of a pair follow the same course through the spaces between the weft threads 5, and each pair of warp threads of a set S follows a course different from the coursesof the other two pairs of the set;

and each pair crosses one weft thread 5 on one face of the fabric and crosses two weft threads 5 on the other face of'the fabric in alternate succession, as shown. This construction enables me to produce a closely woven, and strong backing for the fabric. The short pile threads 3 are arranged. in alineinent with each other between the threads of each pair 6, 'Z and 8, and each short pile thread 3 has its central portion extending over one weft thread 5 and its end portions extending under two weft threads 5 and then up between two adjacent weft threads 5 to form the pile ends 4. This construction insures the proper tying-in'of the short pile threads 3 with the minimum quantity thereof buried in the backing cloth. Further, the pile ends 4 between the two binding warp threads of each and every pair of warp threads are equally spaced from each other by the same number, three, of weft threads, and the short pile threads 3 are so arrangedrelatively to each other that a pile end 4 extends from the back or bottom of the fabric to the top or pile facethereof between each and every two adjacent weft 7 threads 5 within each and every set of pairs of binding warp threads S, as clearlyishown in Fig. 3, thus giving'the desired distribution of the pile ends and preventing the grinning of the backing cloth. It will be observed that two pairs of binding warp threads pass from one face of the fabric to the other and cross from each other between each and every two adjacent weft'threads within each and every set of pairs of binding warp threads S. This is an important feature of my invention as it not only assists in producing a strong, durable and closely woven fabric but it maintains the weft 7 threads all substantially in the same horithreads arranged in adjacent sets of three pairs each, weft threads interwoven with the pairs of warp threads, and pile threads interwoven with the weft threads and arranged in alinement with each other between the threads of each pair of warp threads, each pile thread having two pile ends, each two adjacent pile ends between the threads of the same pair of warp threads being equallyspaced from each other by three weft threads, and each two adjacent weft threads withinfeach'set of pairs of warp threads having a pile end extending between the same from the back of the fabric to the pile face thereof. a o
